Abstract
PSOROSIS of citrus has hitherto not been reported from Malaya. Recent investigations on the possible presence of virus diseases on citrus have shown a large number of mandarin orange trees in Segamat, Johore, to be affected by severe scaling of the bark. Affected trees showed signs of decline. No leaf symptoms, however, have been observed in the field.
